Answer 3

this refers to the class that it is written inside it......

fo example when u have a private variable of type int , called. myInt.
for the setter method (if the parameter has the same name . ) you would use. 'this.myInt' to refer to the variable that is a member of ur class (not the parameter in the setter method)
